Advantages of Nero Lite/Micro edition:
Smaller download size;
Smaller footprint on the system (smaller installation size and much less registry entries written)
10 times faster installation, if not more
Even faster uninstallation, maybe 20 times faster
Uninstallation removes all traces of Nero that were added by Lite/Micro installer.

More info:

Nero Lite will take 250 MB space on your HDD, when all applications are installed. Nero Lite – Micro, will take 140 MB if all applications are installed.

To install Nero Lite (or Micro) completely silent use the switches in this way:

XXXX-XXXX-XXXX-XXXX-XXXX-XXXX-XXXX-XXXX represents your serial. You need to enter it with dashes and WITHOUT any quotes. If you did not type switches correctly or you did not enter serial in correct format installer will not start installation, and you won’t get any message that installation did not start.

Using silent switches is only possible with valid keys. There is no way to combine it with keygen.

Uninstaller is included, but it won’t be showed in Add/Remove programs. You will have the shortcut in Start Menu of it and you can use the installer for uninstall. After uninstall you will probably have to reboot (you’ll get prompt if needed) because some files are in use and can be only deleted after reboot. Do not try to install again Nero if you did not reboot after uninstall, because commands are added which will delete remaining Nero files/folder on next reboot (if prompted for reboot). So, if you don’t get prompt for reboot, you can (un)install as many times as you want without reboot.
